Arduino Opta expansion modules

In my last videos about the Arduino Opta, we noticed that there there is an AUX-port on the PLC. I got a lot of comments in the video asking me whether this AUX-port could possibly be an extension for future modules.
Now, we got the answer. I received a package from Arduino with two expansion modules. Let's take a closer look at them!

I'd love to see how you'd do the automated testing, even in the TwinCAT environment as an example. Thanks for the effort that went into recording and uploading this. Cheers

[@Archfile375]

Additionally, I think @12:00 you are supposed to 'Apply detect config', I think this means 'Apply the detected configuration' to the current project.

You're lucky today! I have a whole course here on KZbin on how to do automated testing using TwinCAT. Check the two episodes about test driven development on my TwinCAT 3 course here on my KZbin.

Thanks as always, is there a way too control a stepper/servo driver with some of the expansion?

[@fiifinenyi2156]

Please how do I interface the opta with an Hmi from a different brand using modbus Rs-485

[@Lachlan.Wright]

Looks good - personally I am mostly interested in the 4-20mA module, but sadly it isn't released yet. Something I am really struggling with: Why would I chose the OPTA solution over something like a CX7000? I really like the CX7000. The main two reasons I can come up with for using the OPTAs are 1. ModbusTCP (LOL Beckhoff) and 2. C++ code.

[@Flamechr]

The c++ part just gives you so many options for modern software development 😂

[@colinspeer2150]

What is your current favorite set up for 4-20 mA sensors?

[@whickervision742]

You can converter 4..20 mA to 1 to 5 volts with a resistor you know. I doubt the analog only module is triple-isolated so no using pH sensors for example.

Thanks a lot for your work here. I will follow your steps to try my opta plc. Would you please make a video on how to install and use two virtual boxes for using two versions of PLC software on one PC. How to make usb ports and ethernet ports working with the PLC hardware.

[@JakobSagatowski]

I did try to use a VM for this video but encountered problems (as can be seen in the video). The VM topic is worth to look into again.

[@chudchadanstud]

beckhoff slices are cheaper. Yes the "PLC" (actually an IPC) is expensive but you get an unlimited 7 day trial and you can probably bypass it with a little Automation Interface and OCR magic.

OMG OMG.. what a great video! Can I subscribe twice?

[@jackallison3884]

Do not buy an opta until they fix the plc ide. For the past year it has been impossible to get time over Ethernet. I have not yet tried 1.0.6 and have my fingers crossed.

[@WilmerAriza]

I can said this: OPTA is the worst device if you turn on the ethernet network. After hours of working without problem the device will go in error mode stop ModBus communication and stop working completely without reason or way to debug. the device needs to power cycle to get out of this status.

[@JakobSagatowski]

I haven't tried any long-term tests with the Opta. Did you try to upgrade it to the latest firmware? (1.1 instead of 1.0, like I did in the video)?

[@yannickasselin1]

I have the same issue. I have an Opta PLC controlling something at home and it completely freezes every now and then. I even added a relay to power cycle the Opta when modbus communication is lost. The relay is controlled from Node-Red on a Raspberry Pi communicating modbus with the Opta. I have not tried the new firmware yet. I will try later.

[@WilmerAriza]

@@JakobSagatowski I still have to do the test.

[@user-me5ct5ui2x]

Just get the real PLC with that price level. Don’t waste your time & money. Get NAIS FP1/2
